Glasses with lens for treating color vision deficiency and method of manufacturing same

Abstract

An ophthalmic lens configured to treat color vision deficiency is presented herein. The lens includes a tinted region containing either or both of a first dye that is configured to absorb at least 50% of incident light in a spectral band between 480 nanometers to 500 nanometers and a second dye that is configured to absorb at least 50% of incident light in a spectral band between 550 nanometers to 580 nanometers. A method of manufacturing such a lens and a process of forming set of eyeglasses by an additive manufacturing process is also presented.

1 . A set of eyeglasses comprising:
 a printed frame having a first opening and a second opening;   a first ophthalmic printed lens for the first opening in the printed frame; and   a second ophthalmic printed lens for the second opening in the printed frame, both of the first ophthalmic printed lens and the second ophthalmic printed lens formed with a first dye therein configured to absorb at least 50% of incident light in a spectral band between 550 nanometers and 580 nanometers.   
     
     
         2 . The set of eyeglasses of  claim 1  wherein both of the first ophthalmic printed lens and the second ophthalmic printed lens formed with a first dye therein configured to absorb at least 50% of incident light in a spectral band between 550 nanometers and 580 nanometers, the first dye therein in a first portion of both of the first ophthalmic printed lens and the second ophthalmic printed lens inside both of the first ophthalmic printed lens and the second ophthalmic printed lens. 
     
     
         3 . The set of eyeglasses of  claim 2  wherein the first portion of both the first ophthalmic printed lens and the second ophthalmic printed lens inside both of the first ophthalmic printed lens and the second ophthalmic printed lens is an inner layer of both the first ophthalmic printed lens and the second ophthalmic printed lens. 
     
     
         4 . The set of eyeglasses of  claim 1  wherein both of the first ophthalmic printed lens and the second ophthalmic printed lens formed with a second dye therein configured to absorb at least 50% of incident light in a spectral band between 480 nanometers and 500 nanometers, the second dye therein in a second portion of both of the first ophthalmic printed lens and the second ophthalmic printed lens inside both of the first ophthalmic printed lens and the second ophthalmic printed lens. 
     
     
         5 . The set of eyeglasses of  claim 4  wherein the second portion of both the first ophthalmic printed lens and the second ophthalmic printed lens inside both of the first ophthalmic printed lens and the second ophthalmic printed lens is an inner layer of both the first ophthalmic printed lens and the second ophthalmic printed lens. 
     
     
         6 . The set of eyeglasses of  claim 1  wherein both of the first ophthalmic printed lens and the second ophthalmic printed lens are formed with a first dye therein configured to absorb at least 50% of incident light in a spectral band between 550 nanometers and 580 nanometers, and a second dye therein configured to absorb at least 50% of incident light in a spectral band between 480 nanometers and 500 nanometers, the first dye and second dye within both of the first ophthalmic printed lens and the second ophthalmic printed lens. 
     
     
         7 . The set of eyeglasses of  claim 6  wherein the first dye is in a first portion of both the first ophthalmic printed lens and the second ophthalmic printed lens, and the second dye is in a second portion of both the first ophthalmic printed lens and the second ophthalmic printed lens, the first portion and the second portion being different portions inside both of the first ophthalmic printed lens and the second ophthalmic printed lens is an inner layer of both the first ophthalmic printed lens and the second ophthalmic printed lens. 
     
     
         8 . The set of eyeglasses of  claim 7  wherein the first portion is a first layer and the second portion is a second layer of both the first ophthalmic printed lens and the second ophthalmic printed lens, and the first layer and the second layer within both the first ophthalmic printed lens and the second ophthalmic printed lens. 
     
     
         9 . A printed ophthalmic lens for eyeglasses comprising:
 a first major exterior surface;   a second major exterior surface; and   an interior portion between the first major exterior surface and the second major exterior surface, the interior portion including a first dye configured to absorb at least 50% of incident light in a spectral band between 550 nanometers and 580 nanometers.   
     
     
         10 . The printed ophthalmic lens for eyeglasses of  claim 9  wherein the first interior portion also includes second dye therein configured to absorb at least 50% of incident light in a spectral band between 480 nanometers and 500 nanometers. 
     
     
         11 . The printed ophthalmic lens for eyeglasses of  claim 10  further comprising a second interior portion that includes second dye therein configured to absorb at least 50% of incident light in a spectral band between 480 nanometers and 500 nanometers, the second portion different than the first interior portion. 
     
     
         12 . The printed ophthalmic lens for eyeglasses of  claim 11  herein the first interior portion is a first layer and the second interior portion is a second layer. 
     
     
         13 . The printed ophthalmic lens for eyeglasses of  claim 11  wherein the first layer and the second layer extend to all the edges of the printed ophthalmic lens. 
     
     
         14 . A process of forming an ophthalmic lens, comprising:
 providing a first liquid resin solution with at least one of   a first dye therein configured to absorb at least 50% of incident light in a spectral band between 550 nanometers and 580 nanometers; and   a second dye therein configured to absorb at least 50% of incident light in a spectral band between 480 nanometers and 500 nanometers; and   forming the lens from the first liquid resin solution using an additive manufacturing process and curing the first liquid resin solution by exposure to ultraviolet light.
